That's the bad two cylinders... How's the compression read? Did U do a leak down? When u pulled the plugs were they wet? Gas? Coolant? Lean crispy? as I like to say.
It could be a crankshaft position sensor maybe... U likely. Just remember fuel, air, spark. Verify those. Compression seems to help too.
5.0 are great engines. I am sure it's fine. Double check and triple check your work
